Attribute

Mandatory

Type

Description

description

No

String

Provides supplementary information about the security group rule.

security_group_id

Yes

String

Specifies the ID of the belonged security group.

remote_group_id

No

String

Specifies the peer ID of the belonged security group.

This parameter is mutually exclusive with remote_ip_prefix.

direction

Yes

String

Specifies the direction of the traffic for which the security group rule takes effect.

The value can be ingress or egress.

remote_ip_prefix

No

String

Specifies the peer IP address segment.

This parameter is mutually exclusive with remote_group_id.

protocol

No

String

Specifies the protocol type or the IP protocol number.

The value can be tcp, udp, icmp or an IP protocol number

port_range_max

No

Integer

Specifies the maximum port number. When ICMP is used, the value is the ICMP code.

The value ranges from 1 to 65535. (The value ranges from 0 to 255 when it indicates the code.)

port_range_min

No

Integer

Specifies the minimum port number. If the ICMP protocol is used, this parameter indicates the ICMP type.

When the TCP or UDP protocol is used, both port_range_max and port_range_min must be specified, and the port_range_max value must be greater than the port_range_min value.

When the ICMP protocol is used, if you specify the ICMP code (port_range_max), you must also specify the ICMP type (port_range_min).

The value ranges from 1 to 65535. (The value ranges from 0 to 255 when it indicates the code.)

ethertype

No

String

Specifies the network type.

The value can be IPv4 or IPv6.

Example Request

Create an outbound rule in the security group whose ID is 5cb9c1ee-00e0-4d0f-9623-55463cd26ff8. Set protocol to tcp, and remote_ip_prefix to 10.10.0.0/24.
